There are various vendors that have support for either TIC, AYIYA or heartbeat. Amongst others, AVM Fritz!Box (own TIC and heartbeat implementation, does require a subnet), Motorola should bring out new routers with full AICCU support soon, DLink is working on it also. Further of course if you have OpenWRT or DD-WRT on a box then it works too. The author of the latter is integrating more tight support at the moment. Astaro has support for AICCU, but do run the latest beta version as the older versions loop AICCU and thus accounts get blocked because of that. We should actually compile a full list once ;) The thing is of course that it all depends on your topology and thus your requirements on how to deploy it.

What I'm looking for is not a border-router, because they often are supplied by the ISP, and sometimes contain voip and/or tvip too, so it can't be replaced by the end user. For instance, I'm getting internet over WiMax, and can't reolace the router, because it connects to an antenna outside of the house; the antenna gets power from the router. I get 6Mb/1Mb through the air, and I could get 10Mb/5Mb, while the copper could barely give 1Mb/256k. The Gogo6 CPE is just plugged in to the LAN, and it then opens a tunnel through the existing router. It just have 1 ethernet and power-input.
